  2. Orbital Maneuvering System - Wikipedia

    en.wikipedia.org/wiki/Orbital_Maneuvering_System

    The Orbital Maneuvering System (OMS) is a system of hypergolic liquid-propellant rocket engines used on the Space Shuttle and the Orion spacecraft.Designed and manufactured in the United States by Aerojet, [1] the system allowed the orbiter to perform various orbital maneuvers according to requirements of each mission profile: orbital injection after main engine cutoff, orbital corrections ...

  3. RS-25 - Wikipedia

    en.wikipedia.org/wiki/RS-25

    The RS-25 engine consists of pumps, valves, and other components working in concert to produce thrust. Fuel (liquid hydrogen) and oxidizer (liquid oxygen) from the Space Shuttle's external tank entered the orbiter at the umbilical disconnect valves and from there flowed through the orbiter's main propulsion system (MPS) feed lines; whereas in the Space Launch System (SLS), fuel and oxidizer ...

    en.wikipedia.org/wiki/Pressure-fed_engine

    It was used on the Space Shuttle orbiter (or simply Space Shuttle) for orbital insertion, manoeuvring the orbiter in space, and the deorbit burn. The AJ10-190 engines could be reused for up to 100 missions. Diagram of an RS-25 (or Space Shuttle Main Engine), that used a twin shaft staged combustion cycle. There were three of these on the back ...

    Payload deployment and retrieval system (PDRS) Responsible for Space Shuttle remote manipulator system (RMS) or "robot arm". Propulsion engineer (PROP) Managed the reaction control thrusters and orbital maneuvering engines during all phases of flight, monitored fuel usage and propellant tank status, and calculated optimal sequences for thruster ...

  7. Spacecraft propulsion - Wikipedia

    en.wikipedia.org/wiki/Spacecraft_propulsion

    With a conventional chemical propulsion system, 2% of a rocket's total mass might make it to the destination, with the other 98% having been consumed as fuel. With an electric propulsion system, 70% of what's aboard in low Earth orbit can make it to a deep-space destination. [23] However, there is a trade-off.

  8. Comparison of orbital launch systems - Wikipedia

    en.wikipedia.org/wiki/Comparison_of_orbital...

    For the list of predominantly solid-fueled orbital launch systems, see: Comparison of solid-fueled orbital launch systems. Spacecraft propulsion [note 1] is any method used to accelerate spacecraft and artificial satellites. Orbital launch systems are rockets and other systems capable of placing payloads into or beyond Earth orbit.

  9. Gimbaled thrust - Wikipedia

    en.wikipedia.org/wiki/Gimbaled_thrust

    In a gimbaled thrust system, the engine or just the exhaust nozzle of the rocket can be swiveled on two axes (pitch and yaw) from side to side. As the nozzle is moved, the direction of the thrust is changed relative to the center of gravity of the rocket. The diagram illustrates three cases.
